FIG. 3 is a flowchart illustrating the displaying of informationregarding the condition of a portable terminal according to the presentinvention. Referring to FIG. 3, the control unit 100 enters into anapplication running mode, i.e. it performs at least one of the variousfunctions of the portable terminal in step 305. When a predeterminedinput signal is generated in the application running mode, the controlunit 100 monitors the transmission of a signal requesting display of thecondition information of the portable terminal, which has been set up inthe course of FIG. 2, from the key input unit 110 in step 310. When thesignal requesting display of the condition information is received, thecontrol unit 100 checks the display type of the condition information instep 315. Although not shown in the drawing, the user may set up thedisplay type as desired. For example, the condition information may bedisplayed on the display unit 140 after pausing the application.Alternatively, the condition information may be displayed in a pop-upwindow.

After checking the display type in step 315, in step 320, the controlunit 100 pauses the application currently-running. The control unit 100controls the display unit 140 so as to display the condition informationas selected by the user in step 325. In step 330, the control unit 100checks for the arrival of a predetermined time, at which the display ofthe condition information is to end. Particularly, the display of thecondition information can be terminated when an input signal isgenerated by a confirmation key, for example, while the conditioninformation is displayed. Alternatively, the user may preset the timefor terminating the display of the condition information so that thedisplay is terminated when the time arrives. It is assumed that thedisplay of the condition information is terminated when thepredetermined time arrives. When it is confirmed in step 330 that thepredetermined time for terminating the display has arrived, the controlunit 100 proceeds to step 335 and terminates the display. The controlunit 340 resumes the application, which had been run before thecondition information was displayed, in step 340.

According to the present invention, at least one piece of information isdisplayed in accordance with the user's selection. For example, when asignal requesting display of condition information is detected, thecontrol unit 100 displays a plurality of pieces of condition informationbased on the priority.

FIG. 4 is a flowchart illustrating the displaying of informationregarding the condition of a portable terminal according to anotherembodiment of the present invention. Referring to FIG. 4, the controlunit 100 enters into an application running mode, i.e. it performs atleast one of the various functions of the portable terminal in step 405.When a predetermined input signal is generated in the applicationrunning mode, the control unit 100 monitors the transmission of a signalrequesting display of the condition information of the portableterminal, which has been set up in the course of FIG. 2, from the keyinput unit 110 in step 410. When the signal requesting display of thecondition information is received, the control unit 100 checks the itemsof the condition information, which have been selected by the user inthe course of FIG. 2, in step 415.

In step 420 the control unit 100 checks the priority of the items of thecondition information, which have been checked in step 415, in step 420.It is assumed in the that the items of the condition information, whichare selectable by the user, include current date and time, receptionsensitivity, and battery level. In addition, the priority of theselected items is in the following order: current date and time,reception sensitivity, and battery level. The control unit 100 checksthe display type of the condition information in step 425 in a mannersimilar to that of step 315 shown in FIG. 3.

The control unit 100 determines how many signals requesting the displayhave been detected in step 410. Particularly, the control unit 100decides if a single signal requesting the display of the conditioninformation has been detected in step 430. If so, the control unit 100displays information regarding the current time, which has top priority,in accordance with a preset display type in step 435. If not, thecontrol unit 100 proceeds to step 440 and decides if two signals havebeen detected. When it is confirmed in step 440 that two signals havebeen detected, the control unit 100 displays information regarding thereception sensitivity, which has the second-highest priority, inaccordance with a preset display type in step 445. When it is confirmedin step 440 that more than two signals have been detected, the controlunit 100 proceeds to step 450 and determines if three signals have beeninputted. If so, the control unit 100 displays information regarding thebattery level, which has the third-highest priority, in accordance witha preset display type in step 455.

Although it is assumed that the procedure ends without display of thecondition information when at least three signals are inputted, thecontrol unit 100 may request that the user re-enter signals in thatcase. Alternatively, the condition information may contain at leastthree items, which are displayed when corresponding key input signalsare generated.

After displaying information regarding one of a current time, receptionsensitivity, and battery level in accordance with the number of inputtedsignals, the control unit 100 checks for the arrival of a predeterminedtime, at which the display is to end, in step 460. If the predeterminedtime has not yet arrived, the control unit 100 proceeds to step 465 andcontinuously display the current item of the condition information. Uponarrival of the predetermined time, the control unit 100 terminates thedisplay in step 470.

Although it is assumed that the display of the condition information isterminated when a predetermined display termination time arrives whilethe information is being displayed, the display may also end when theuser operates a confirmation key, for example, during the display.

As mentioned above, the present invention is advantageous in that, evenwhen an application is run by a portable terminal, information regardingthe condition of the terminal can be displayed on the display unit asdesired by the user.
